TROLLEY.

SPECIFICATION forming part of Letters Patent No. 621,399, dated March 21, 1899;. Application filed December 6,1898. Serial No. 698,451. (No model.)

-ing like parts.

This invention has for its object to improve the construction of trolleys for electric cars to the end that it may be self-adjusting and accommodate itself to the trolley-wire, which may be located high above the car in certain places and but a short distance above the car in other places, the trolley-pole in the former instance projecting at an angle of, say, fortyfive degrees or less from a perpendicular and in the latter instance occupying nearly a horizontal position, and in all positions of the trolley the trolley-head will be prevented from coming in contact with the wire.

In accordance with this invention the trolley-head, which bears the trolley-wheel, proj ects upwardly and rearwardly from the pole at an oblique angle, and said head is swiveled to the pole, and means are provided for guiding and controlling its position, and in constructing said head it will be formed or provided with a spindle which enters a hole in the pole, and to augment the obliquity of the trolley-head and assist it in performing its functions its spindle is also disposed more or less obliquely to the pole.

The trolley-head is formed with a base or shoulder which rests on the pole, and said head projects from said baseat a point at the rear side of the center, and the spindle extends down through the pole from the center of said base, but is disposed obliquely to the plane of of the base.

As a means of guiding and controlling the position of the trolley-head it is herein shown as having attached to it an arm, which is located beneath the pole, and the trolley-rope, which is attached to the pole, passes through an eye formed in said arm, or it may be otherwise adapted to engage it. The contact-springs, which bear upon or-against the trolley-wheel, pass through openings made in the sides of l; and Fig. 3, a plan View of the arm attached to the trolley-head, which forms a cooperative part of the means employed for guiding and controlling its position.

The trolley-pole a, of any usual or suitable construction, has a socket at its upper end, into which is driven or otherwise secured an end piece b,which when secured thereto forms a part of said pole. The trolley-head c is composed of two side pieces formed integral and located a short distance apart to present a yoke or frame to support the bearings for the trolley-wheel d. The side pieces of the trol ley-head c are also formed integral with a base or shoulder a, which bears directly on,

the pole, and said side pieces extend upwardly and rearwardly from said base, thereby occupying a position more or less oblique to the pole. Furthermore, the said oblique side pieces project from the base 0 from a point at the rear of the center of the said base.

A spindle c is formed integral with said trolley-head, which extends down from the base 0' through a hole formed in the pole, and said spindle projects from the center of said base and is disposed obliquely to the plane of the base. It will thus be seen that the trolleyhead is swiveled to the pole and may be turned freely on the axis of the spindle. With the parts thus constructed and arranged it will be seen that when the pole is in a horizontal position, or nearly so, the front side of the base 0' will be elevated above the rear side thereof and that the trolley-wheel will bear upon the wire Without permitting the trolley-head to engage said wire, and, furthermore, it will be seen that when the pole is raised to a position, say, forty-five degrees from a perpendicular the trolley-wheel will then engage the wire in substantially the same manner. Thus the height of the wire above the car becomes of no consequence.

The projecting end-of the spindle 0 which passes down through a hole in the pole, has

attached to it an arm 0 which occupies a pcsition beneath the pole, and the opposite end of said arm has a hole through it, through which passes the usual rope e, which is attached to the pole. By means of said rope the trolley-head may be guided and its relative position to the pole controlled.

The contact-springs f, which bear upon or against the trolley-wheel, pass out laterally through openings in the sides of the trolleyhead, as shown in Fig. 1, and the lower ends of said springs are attached to the outside of the trolley-head.

Instead of forming all parts of the trolleyhead integral, as above stated, they may be separately formed and secured together in any desirable manner.

\Ve do not desire to limit our invention to the employment of all the specific features herein enumerated, as some of them my be eliminated and yet many advantages secured.

\Ve claim- 1. A trolleypole having an end piece with a hole through it, a head bearing a trolleywheel, having a shouldered base bearing on the pole and having a spindle projecting obliquely from said base which is contained in said hole and means for turning said head, substantially as described.

2. A trolley-pole having an end piece with a hole through it, a head bearing a trolley- 30 wheel, having a shouldered base bearing on the pole and having a spindle projecting obliquely from said base which is contained in said hole and an arm attached to the projecting end of said spindle and a rope connected to the pole which engages said arm, substantially as described.

3. A trolley-pole, a head projecting rearwardly and upwardly from the top of the pole and having a spindle passing obliquely through said pole, an arm connected to the projecting end of said oblique spindle and a rope connected with the pole which engages said arm, substantially as described.

4. A trolley-pole, a trolley-head having a base or shoulder v bearing on the pole, and havinga spindle projecting from said base obliquely to the plane of the base, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
